Thanks for posting this. This is a nice piece - if I had to comment constructively on anything, it would be that the shadows (blacks) are crushed a bit too much - dark detail is missing at least on my MacBook Air. Good luck with the deal though and make sure that buyer understands what seller is selling and why it commands an appropriate price. I would sell a piece like that here in New England locally for no less than $1500 USD and certainly considerably more to a regional or national media company.
The market and markket pricing for our commercial work is being made by us here and now. We've may only have one shot to get it right. There are a lot of hobbyists looking for beer money (hicc-up) selling poor footage to low ball, low quality buyers. Work hard to set the proper precedence.
Tit for tat .. have a look at a similar piece I did ...
